Neco 2023 Physics Question 44
Practice objective / multiple choice question 44 from the 2023 Neco Physics examination.
A steel rod of length \(L_{0}=2.00\,\text{m}\) at \(20^{\\circ}\text{C}\) has a coefficient of linear expansion \(\\alpha = 12 \times 10^{-6}\,^{\\circ}\text{C}^{-1}\). It is heated until its length becomes \(2.10\,\text{m}\). The rod is then uniformly cooled to a temperature that is \(30^{\\circ}\text{C}\) lower than the original temperature. Find the final length of the rod (in metres, to three significant figures).
